I like this track!
Elevation changes in sharp, blind corners are just not every players affair. Placing the grandstands in such corners seems to make sense, you can see them as a driver even when you're coming from a deeper part of the track and it gives a realistic look.

Thanks for the review and thoughts, Bongo! Yeah -- in previous versions I've tried to mellow out the elevation changes in the corners. But I always found that the even small changes have some sort of ripple effect on every other turn on the course due to the way the track maker app is set up. Also, the track always seemed to lose some of its character. Trying to please everyone always ends up pleasing no one...
